About the project:
- Ministry of Railways, Government of India has entrusted Rail Vikas Nigam Ltd (RVNL), a PSU under Ministry of Railway, with the responsibility of execution of 198 km long single line electrified new BG Mangliya gaon (Indore) – Budni Rail Line infrastructure project, to be financed by Govt. of India, in the State of Madhya Pradesh, Rail Vikas Nigam Ltd (RVNL) is the Implementing Agency (IA) of the project.
- Name of the Assignment: “Detailed Design Consultancy for Tunnel and Viaduct including Geotechnical Investigation and Project Management Consultancy for Construction of Tunnel, Viaduct, ROBs / RUBs and Waterways in connection wit Construction of electrified new BG railway line between Mangliya Gaon (Indore) to Budni stations (198 KMs) of West Central Railway and Western Railway in Madhya Pradesh State, India.” .
- The services of the Consultant would be required in both stages of the project namely:
- Pre Construction design stage which include review of investigation works, planning, detailed design, preparation of bid documents of construction works, etc.
- Construction stage which include design support during construction and project management services commencing from award of the construction contract to completion of work including stipulated defect liability period.
Scope of Services:
The services to be provided shall include all provisions which shall cater for safe and comfortable running of freight as well as passenger services with minimum Maintenance. General Consultant (GC) or authorized representative of RVNL will scrutinize the reports, concepts, designs and drawings submitted by Consultant and approve them as “Fit for Construction”. The services are listed below under different categories but the services required may be overlapping also.
The scope of the consulting services for each of the major category listed below includes, but is not limited, to the following activities:
- Tunnel Works: Planning and design philosophy for tunnel shall be as under
- Planning: Planning of a tunnel work would require the interdependent participation of the following discipline, at a minimum:
- Geology
- Geotechnical engineering
- Excavation technology i.e. Drill and blast, road header etc
- Design of supporting structural elements, including long term behaviour
- of materials.
- Contract principles and law
Although the experts in each of these disciplines may be responsible only for their specific area of knowledge, the decision on the main design features should be the outcome of the cooperative integration of all the discipline thus, ensuring that the project, in all its details, has been developed in unity, and not as the consecutive addition of the separate work of each of the experts.
Risk Assessment and Management: The consultant shall employ a formalized procedure to:
- Identifying hazards and associated risks, through Risk Assessments and the management of risk to ensure their reduction to a level “as low as reasonably practicable” shall be integral considerations in the planning, design, procurement and construction of Tunnel and associated Works. So far as it is reasonably practicable, risk should be reduced through appropriate design and construction procedures.
- Explicitly allocate responsibility for risk management to relevant parties to a contract so that they are addressed adequately and appropriately in the planning and management of a project and that appropriate financial allowances can be made.
- Identify and evaluate the hazards; and identify and quantify their consequent risks throughout all stages of a project.
- Prepare Risk Registers to identify and clarify ownership of risks and to detail clearly and concisely how the risks are to be allocated, controlled, mitigated and managed. To develop the systems to track risks and to enable the management and mitigation of risks through contingency measures and controls; to be monitored through all stages of a project.
- Risk Registers shall be ‘live’ documents that would be continually reviewed and revised as appropriate. The consultant shall identify hazards, consequent risks, mitigation and contingency measures, proposed actions, responsibilities, critical dates for completion of actions.
Tunnel Design issues:
- The design process should be such that, the risk of failure or damage to the Tunnel and associated Works or to a Third Party from all reasonably foreseeable causes, including health and safety considerations, is extremely remote during the construction as well as during the design life of the Tunnel and its associated Works.
- Risks from high consequence, low frequency events that could affect the works or a Third Party must be explicitly considered in the design process.
- The Designer shall prepare documentation which shall include but not necessarily be limited to:
- A description of the element to be designed.
- The design requirements and criteria to be adopted.
- A geotechnical assessment that shall evaluate the geological and geotechnical information available (including the presence or generation of harmful gases), ground and groundwater contamination) and ascribe design values for the pertaining assessed ground and ground water conditions for the purpose of design with justification in the light of information provided;
- A description of the method of design (including reference to any applicable Codes and/or Standards).
- A description of the method(s)of analysis to be used for the design and justification thereof a Design Risk Assessment which shall consider the impact on the design and hence its implementation (not only on the Tunnel and associated Works but also to Third Party such as nearby buildings & structures, water bodies etc.,) of any realistic variation in the design criteria and/or design values adopted, based on the information available in relation to the anticipated/proposed Method (s) of construction. The Design Risk Assessment shall take account of potential failure mechanisms and include mitigation/contingency measures appropriate to the anticipated/proposed method(s) of construction.
- The checking procedure to be implemented for the design.
- Calculations, analyses and assessments stages of construction. should also consider intermediate
- The design process shall include, where appropriate, sensitivity studies to assess the impact of:
- Construction tolerances.
- Variation in geotechnical design values.
- Variation in materials characteristics.
- Variation in workmanship and geometry.
- Methods of construction & implementation of mitigation/contingency measures.
- Natural perils exposure in the region of the project such as flood, storm, seismic effects.
- The design process shall include an assessment of the impact of construction on Third Party infrastructure i.e. Buildings & structures, water bodies etc.
Geotechnical Baseline Report:
- Preparation of Geotechnical Baseline Report (GBR) for tendering requirement of the tunnel construction contract in a collaborative manner with geologists, tunnel designers and civil engineers.
- The baselines should be meaningful, reasonable and realistic, and to the maximum extent possible should be consistent with the available factual information contained in the Geotechnical Data Report (GDR).
